Now that the preliminary excitement of my ingenious idea wore off, I'm ready to share it and accept the harsh reality of any shortcomings... but seriously.
For a while now, I've been been working on optimally integrating my 3 channel...

[quote user="jessie.dazzle"] Regarding the Mid-Bass : If these guys are using the main block as a Mid-Bass horn (as Romy's illustration suggests), then the story is getting interesting, and the plot is definitely thickening... It would however seem i...

Romy,
First thing I would try is a single dot of Elmer's White Glue applied in the exact center of the dome, on the outside. The dot would be the size of a round wooden toothpick, cut off at the beginning of the taper. Dipped in the glue, the end of...

[quote user="JLH"] Other than being completely ridiculous in appearance, this guy didn’t even bother to time align any of the drivers. [/quote]
This exactly what is the most fun in that system! Sometime people do not do the time alignment because it...

I have written in past about my lack of love to the BMS drivers. The crazy, as far as I concerned “annoyingly wiling” angeloitacare brought this subject to this forum while he was galloping across Web, “picking from graves” about his new dB-Design’s ...

[quote user="skushino"] • total horn length (incl. back chamber) shall not exceed 1,00m • the horn shall have conical approximation of a hyperbolic flare contur with m=0.6 • the horn shall have a 5/16 mouth size of a free space horn •&...

Romy,
In all your search for better sound quality, did it ever occur to you that the greatest time-domain distortion might occur at the other end of the signal chain?
The problems you perceive at the upper end of the spectrum are as likely problems...

Dominic, I did not use Lowtheres on my own and am familiar with Lowtheres only by observing of what other people do. Unfortunately, among what I have seen. Lowther was used in some strange ways. For whatever reasons people feel that absences of a cro...

[quote user="stuck.wilson"] I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of my system a GREAT DEAL MORE without the absurd notion that 20-20k is wh...

Hello again, Romy...
I totally agree with you about changing the rear chamber volume. It makes a very positive improvement in extension as well as quality. Also, I had never dreamed of a driver with a variable compliance resulting in a variable...
|
Well, whatever you do with your loudspeakers of with you whole playback system is kind of irrelevant if your drivers are not right. In my view the drivers are the very much heart of playback but in case of High-Efficiency and particularly horn-loaded...
|
I am on record as not liking back loaded
horns:to be effective at bass frequencies, a BLH needs to be as long
as a FLH would be; I've yet to see a BLH, with the possible exception
of the Tannoy Westminster, that actually has a long enough horn ...

[quote user="RF at Ona"] Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers...

[quote user="de charlus"]Romy, do you have first hand listening experience of these YL drivers? If so, in what sort of installation? [/quote]
Nope, I did hear neither YL drivers nor ALE driver, as least consciousnessly.

[quote user="noviygera"]My mid/upper horns play down to 190Hz. That is -- 188Hz is the Fs of the mid. It's a horn loaded a 10" Precision Device driver. So I need a section (or two sections) to cover the bottom (below 190hz). [/quote]
Herman, i...

[quote user="Romy the Cat"] It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. S...

Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.
[quote user="be"] The time alignment will depend on the geometrics of horn set up and listening posit...

This is the last article in the planed overview. Here I would like to cover options available among commercially available High-Efficiency systems. As you might expect it will not be too exiting.
In a ways commercial systems inherent all problems of...

Oops,
I'll send the images again once back at work on Monday.
The thraot size will be 7 inches.
Yes I have thought about paying someone else to do the work, but that sort of skilled labor is super expensive around here.
And... Yesterday ...

Here is an interesting setup. It is nowhere in Moscow Russia. I did not hear it but it does not mean that we can’t analyze what the authored was trying to accomplish.
It is 3-way installation. Bass looks like dual G...

Today I spent a few hours to calibrate the Macondo and Milq.
One of the drivers from Macondo was gunner and the rest was more of less stable.
I did some initial measurements. It was not impressive. I do have approximately
3-4 db deficiency on left...

When many of your will experiment with building and listening your own horns and spend countless amount of time by sketching a configuration of your new horn assembly you then might come to an observation that Macondo Upperbass topology is very s...

It is ended a very nice. Today I have calibrated the playback,
fine the right phasing for the channels and figure out how to integrate them.
The direct radiator midbass runs remarkably flat to the rest in the system.

Wow, THAT IS BOLD!!!! The 45Hz how from 7” throat – that is very-very cool and very positively-obnoxious.

The “best midrange comes from compression drivers”. I see somebody like Haralanov would be very much opposed to this comment. The irony is that I would be opposed as well to this comment. I would say that the best midrange at over 107dB sensitiv...

[quote user="Jeffrey Jackson"] Also, I had never dreamed of a driver with a variable compliance resulting in a variable free air resonance... such a toy would be wonderful with custom midbass and bass horns... [/quote]

The relationship between horn-loaded loudspeakers users and honk sound that some horns tend to produce migh be stratified by the following sequential categories.
